The technical solution adopted for the present invention to solve the technical problems is:A kind of steel framework of Novel angle iron connection friction energy-dissipating Set a roof beam in place Column border node, including two post, beam-ends, upper and lower two angle cleats, left and right connection channel-section steels being welded on post, the welding Connected as one in the connection channel-section steel on post with beam-ends by connecting bolt;The post, beam-ends, angle cleat pass through connecting bolt Connect as one;The beam-ends is made up of top flange, lower flange, web, the top flange, lower flange, is all provided with length on web Circular hole, it is allowed to which connecting bolt slides in hole;The angle cleat, the link slot steel capital being welded on post are provided with circular bolt Hole.
Further, the angle cleat and the contact surface of lower flange, the connection channel-section steel and beam-ends that are welded on post on beam-ends The contact surface of web is friction treatment face, for for lower flange, the connection channel-section steel being welded on post on angle cleat and beam-ends Relative slip provides frictional resistance with web plate.
Further, ribbed stiffener is set at the angle cleat, and the purpose is to angle cleat is occurred with lower flange on beam-ends Yield failure does not occur for angle cleat before relative slip.
In use, beam-ends is lifted into installation site, web plate is inserted among two connection channel-section steels for being welded in post, Beam-ends is linked together with being welded in the connection channel-section steel of post using connecting bolt, and passed through post and beam-ends using connecting bolt Upper and lower two angle cleats link together.After tightening the certain pretightning force of nut application, lower flange is with being connected on the beam-ends Between angle steel, web plate and be welded in post connection channel-section steel between produce thrust, so as to by the frictional couple between component To resist beam-ends moment of flexure.Under general stressing conditions, due to the prestressed effect of bolt, lower flange and angle cleat on beam-ends, Frictional force between web plate and the connection channel-section steel for being welded in post is by the relative slip between limiting each contact surface, now beam The displacement at end mostlys come from the deformation of beam-ends itself, and node serves as general bean column node and provides necessary bending rigidity.Work as knot When structure bears strong geological process or serious disaster caused by a windstorm, the moment of flexure that beam-ends is born exceedes the frictional force of frictional force offer between component It is even, start to produce relative slip between contact surface, node starts as fulcrum to be turned using the contact position of the lower flange of beam-ends and post It is dynamic.Mainly connect during this by beam-ends top flange with angle cleat, web plate with being welded in the connection channel-section steel these two pair of post Sliding friction between contacting surface reaches the effect of power consumption, node engaging friction power consumption stage.Therefore, present invention considerably reduces ground Plastic deformation at shake or disaster caused by a windstorm interior joint, have simple structure, practical, highly energy-consuming, damage after shake it is small, be easily repaired Advantage.
